According to the heat dissipation structure for the bulb lamp, through air circulation channels which are formed by gaps on a surface cover of a light emitting diode (LED) bulb lamp, through holes in a substrate of a shell and heat dissipation holes on the side of the shell, which are communicated in sequence, and by combining two heat dissipation methods of heat radiation and air convection, heat which is generated when the LED bulb lamp works can be dissipated efficiently, and a heat dissipation effect is extremely excellent.

Description

The bulb lamp radiator structure

Technical field

The utility model relates to lighting field, mentions a kind of bulb lamp radiator structure especially.

Background technology

In lighting field, emerging LED semiconductor lighting technical application is just increasingly extensive.In the LED light fixture, having a kind of is the LED bulb lamp that is applied to lighting of home.The structure of existing LED bulb lamp comprises all that generally E26 hickey, metal shell and the face shield that is connected and installed successively together, led light source plate are installed on the substrate in the shell, and enclosure also is equipped with the LED driving power simultaneously.In the work of LED ball bubble, LED can produce caloric requirement and distribute, and existing LED bulb lamp structure all is that the heat that LED produces is conducted on the shell, distributes through thermal-radiating mode.This radiating mode is more single, and radiating effect is relatively poor, the LED bulb lamp in use for some time, the lamp body temperature increase is higher, and there is bigger adverse effect in life-span of LED.

The utility model content

To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of bulb lamp radiator structure, and it has the advantage of good heat dissipation effect.

To achieve these goals, the technical scheme that the utility model adopted is: the bulb lamp radiator structure comprises the shell of heat conduction; Be individually fixed in the face shield and the interface at shell two ends, also comprise the power shelf that is inserted in the container cavity of shell center, an end that joins with face shield on the said shell has substrate; Be fixed with light source board on the said substrate; It is characterized in that said face shield side offers a plurality of breach, offer a plurality of through holes on the said substrate; The side of said shell offers a plurality of louvres, and said breach, through hole are connected successively with louvre and form the air-flow circulation canal.

Preferably, all have the double-screw bolt of heat conduction on each LED bulb of said light source board, said light source board is installed on the mount pad outstanding on the said substrate through double-screw bolt.

Preferably, be connected with heating column on the said double-screw bolt, said heating column is connected in the end face tapping of power shelf.

Preferably, said heating column has cavity, and its side offers pore.

The utility model is compared the advantage that is had with prior art: through offering a plurality of breach in the described face shield of LED bulb lamp side; Offer a plurality of through holes on the said substrate; The side of said shell offers a plurality of louvres; Said breach, through hole are connected successively with louvre and form the air-flow circulation canal; After the heat of LED bulb generation conducted to the shell substrate through light source board, the part heat can distribute through the shell own radiation, and most of heat can distribute via above-mentioned breach, through hole and cycling through with cross-ventilated mode of louvre composition.The utility model is through the radiating mode that heat radiation combines with cross-ventilation, and the heat that the work of LED bulb lamp is produced distributes greatly efficiently, and radiating effect is very excellent.

The specific embodiment

The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.

Embodiment, see that Fig. 1 is to shown in Figure 3:

The utility model is a kind of bulb lamp radiator structure, comprises the shell 10 of heat conduction, is individually fixed in the face shield 20 and interface 30 at shell 10 two ends; Also comprise the power shelf 40 that is inserted in the shell 10 center container cavities; An end that joins with face shield 20 on the said shell 10 has substrate 11, is fixed with light source board 50 on the said substrate 11, it is characterized in that; Said face shield 20 sides offer a plurality of breach 21; Offer a plurality of through holes 12 on the said substrate 11, the side of said shell 10 offers a plurality of louvres 13, and said breach 21, through hole 12 are connected successively with louvre 13 and form the air-flow circulation canal.The utility model is through offering a plurality of breach 21 in the described face shield of LED bulb lamp 20 sides; Offer a plurality of through holes 12 on the said substrate 11; The side of said shell 10 offers a plurality of louvres 13; Said breach 21, through hole 12 are connected successively with louvre 13 and form the air-flow circulation canal; After heat that LED bulb 51 produces conducted to shell 10 substrates 11 through light source board 50, the part heat can distribute through shell 10 own radiations, and most of heat can distribute via cycling through with cross-ventilated mode of forming of above-mentioned breach 21, through hole 12 and louvre 13.The utility model is through the radiating mode that heat radiation combines with cross-ventilation, and the heat that the work of LED bulb lamp is produced distributes greatly efficiently, and radiating effect is very excellent.

For the heat on the LED bulb 51 is conducted on the substrate 11 of shell 10 quickly; The double-screw bolt 52 that all has heat conduction on each LED bulb 51 of said light source board 50; Said light source board 50 is installed on the mount pad 14 outstanding on the said substrate 11 through double-screw bolt 52; This structure makes the heat of LED bulb 51 closely contact with heat conduction with the plane of mount pad 14 through double-screw bolt 52, and heat just can conduct to apace on the shell 10 and distribute.

In order further to improve radiating effect; Be connected with heating column 60 on the said double-screw bolt 52; Said heating column 60 is connected in end face perforate 41 places of power shelf 40, so the heat on the double-screw bolt 52 also can conduct on the heating column 60, also can conduct on the power shelf 40 simultaneously; Improved area of dissipation, radiating effect is better.Simultaneously; Said heating column 60 has cavity 61; And its side offers pore 62; Make the perforate 41 on breach 21, the through hole 12 on the substrate 11, the pore 62 on the heating column 60 and power shelf 40 end faces on the face shield 20 form another circulation canal, increase cross-ventilation speed, improve radiating effect.

The bulb lamp radiator structure of utility model, it has the very excellent effect of radiating effect.
